Transfer speculation continues to mount as multiple reports in recent days have linked Said El Mala with a move to Dortmund. The midfielder, currently playing for Cologne, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Man Utd, Brighton and Manchester City decide to make a formal offer of their own in the coming days. So far this season, Dortmund are steady at both ends (1.75 goals scored per game, 0.92 goals conceded per game). The role for Said El Mala would be to keep that balance while lifting performances across the pitch. Reports suggest Dortmund are monitoring Fisnik Asllani, Angelo Stiller and Nathan De Cat whereas Cologne have not been associated with other players at this stage.
